PLATE XXXIII. 



Sphenopteris (Eremopteris) artemisiaefolia (?). 

 (Steenb.) Sch. Yar. 



It is with much doubt that this remarkable specimen 

 is referred to this group — one which includes forms so 

 delicate as Sphenopteris crithmifolia of Lindley and 

 Hutton, and others, more like the present one, such as 

 Sphenopteris stricta of Sternberg. 



One of the authors of the " Fossil Flora." in a pencil 

 note, seems to hint that this may possibly be the im- 

 pression of an alga. 



This and the three following Plates are from drawings 

 by Mr. T. W. Embleton. The specimens represented 

 came from the shale forming the roof of the High Main 

 at Fawdon Colliery.
